This tip comes to us all the way from our friend Nicolas Menu in Neuchâtel Switzerland regarding this initially puzzling error.
You may have noticed this warning when begining to create a new subassembly in the Subassembly Composer (SAC) after adding a geometry point or other components, then attempting to add a code to these components. As soon as you enter the code (XXX being our example code) you will get a warning sign indicating:
“The code XXX is not a valid parameter or variable"
Hope this helps, and thanks again to Nicolas for providing this tip to share on Being Civil!!
